目的:研制白喉棒杆菌核酸检测试剂用国家参考品。方法:将6株白喉棒杆菌和10株非白喉棒杆菌代表性菌株在各自适宜的环境下培养,经菌株鉴定后,制备灭活菌液,对候选参考品进行均匀性和稳定性的评估以及准确性、特异性、重复性和最低检出限的验证研究,并组织3家实验室进行协作标定。结果:研制出白喉棒杆菌核酸检测试剂用候选参考品,由6个阳性参考品、10个阴性参考品、最低检出限参考品和重复性参考品组成。证实该候选参考品均匀性及稳定性良好,准确性、特异性及重复性好,最低检出限可达1.0×103~1.0×104个菌·mL-1。协作标定结果也进一步表明阳性、阴性、重复性和最低检出限候选参考品均符合国家参考品的各项要求。结论:研制出的白喉棒杆菌核酸检测试剂参考品,可用于相关试剂盒的质量控制和评价。 |

Objective: To develop national reference for Corynebacterium diphtheriae Nucleic Acid TestKit. Methods: Six strains of C. diphtheriae and 10 strains of non-C. diphtheriae were cultured in the suitableenvironment. After identification, the inactivated bacterial solution was prepared. The reference samples wereevaluated for uniformity and stability. The accuracy, specificity, repeatability and minimum detection limit ofthe reference were verified. Three laboratories were organized to carry out collaborative calibration. Results:A national reference for Corynebacterium diphtheriae Nucleic Acid Test Kit was developed, which included6 positive references, 10 negative references, minimum detection limit references and repetitive references.The national reference showed good uniformity and stability. The minimum detection limit is 1.0×103-1.0×104bacteria·mL-1. The results of collaborative calibration also showed that the candidate reference materials ofpositive, negative, repeatability and minimum detection limit met the requirements of national reference materials.Conclusion: A national reference was successfully developed, which can be used for the quality evaluation of Corynebacterium diphtheriae nucleic acid detection reagent. |
